The show really touches on a lot of issues created by the culture of consumption that is so prevalent in "developed" nations. How we seek out "deals" and quantity over quality which perpetuates the cycle of cheap clothing imports. Our desires support low wages abroad and are a big reason why garment manufacturing was outsourced to other countries from the start. Anyway, it is a very interesting look at a side of fashion that most of us would never have the chance to see otherwise. While researching the show I found one website that stated some of the factories shown were for Zara, H&M, French Connection and Gap. Whether that is true or not is debatable, but it's food for thought.
If you'd like to watch the show, I have linked to segments of one the episodes that have been uploaded to YouTube below. Consider yourself warned: a couple of the participants are incredibly whiny and downright offensive in some instances. Still, I think "Blood, Sweat and T-shirts" does get it's point across in the end.
